Which of the following is the optimal range of water temperatures for cleaning dishes in a dishwasher?
- A.
90 to 110 degrees Fahrenheit.
- B.
110 to 130 degrees Fahrenheit.
- C.
140 to 160 degrees Fahrenheit.

Which of the following is a characteristic of a 2-story balloon-framed house?
- A.
The exterior wall studs extend from the mudsill to the eave.
- B.
The exterior wall studs extend from floor to floor.
- C.
It permits the use of smaller dimensional lumber for exterior framing.
- D.
It permits a speedier method of exterior framing construction.
Correct Answer
A. The exterior wall studs extend from the mudsill to the eave.Explanation
A characteristic of a 2-story balloon-framed house is that the exterior wall studs extend from the mudsill to the eave. This means that the wall studs run continuously from the bottom of the house to the top, providing structural support for the entire height of the building. This method allows for a more efficient and cost-effective use of lumber, as smaller dimensional lumber can be used for the exterior framing. Additionally, this construction technique allows for a faster and easier method of framing the exterior walls.Rate this question:

The formula for Ohm's law is:
- A.
Volts= Amps/ohms.
- B.
Ohms = volts/amps.
- C.
Amps= volts/ohms.
- D.
Ohms = amps/volts.
Correct Answer
C. Amps= volts/ohms.Explanation
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. The formula Amps = volts/ohms represents this relationship, where Amps represents the current flowing through the conductor, volts represents the voltage applied across it, and ohms represents the resistance of the conductor. This formula allows us to calculate the current flowing through a conductor when the voltage and resistance are known.Rate this question:
